One small step for mankind. Keep in mind there's still a lot of GRU that needs to be refurbished. I'd be happy if there was air conditioning at the baggage claim areas, and an efficient transfer desk. GIG's Terminal 2 is updated, to a degree, to accommodate virtually all international flights, and Terminal 1 seems to be undergoing a long process of remodeling, with many corridors lined with boarding when I passed through in early April.
At least there's progress. The work on the airport in Fortaleza, which we use a lot, was first scheduled to be done in time for the WC and will now be done in 2016.
